摘　　要：采用光电开关和集成电路NE555设计出了一种反射式凸轮轴位置传感器,配合信号转子和反光膜,成功地将凸轮轴位置和转速转化成方波信号,送给ECU。这种传感器具有波形好、抗干扰能力强、安装灵活方便等优点,既可以安装在凸轮轴上,也可以安装在分电器轴或发动机曲轴上。The author introduces a reflective camshaft position sensor using photoelectric switch and the integrated circuit module NE555. With the signal rotor and the reflective membrane, it successfully transforms the camshaft position and the rotate speed into square signal, and then transports to ECU. This sensor has better waveform, high anti-jamming ability and it is easy to install： it can be fixed not only on the camshaft, but also on the shaft of the distributor or on the engine crank.
